Weed scientists are confident of increasing production through agricultural technology, including herbicides, but do not must ask if the moral obligation to feed people is sufficient justification for the benefits and harms achieved. A continuing, rigorous examination of the science’s goals that leads to appropriate change is advocated. Weed scientists have a research consensus - a paradigm - Weeds must be controlled. Herbicides are the best control technology. Agriculture's practitoners should discuss the necessity and risks of their technology. Discussion must include scientific evidence and value-laden arguments.

I write because I am concerned that I and my agricultural colleagues have avoided addressing the moral dimension of the environmental and social problems we have contributed to. I hope for an exchange of ideas about agriculture's moral dilemmas. I encourage my readers to engage in a collective conversation about the dilemmas and avoid remaining in what Merton calls "the collective arrogance and despair of his own herd." If those engaged in agriculture continue to ignore and fail to realize our common difficulties they will be addressed and resolved by societal pressure and political action, which may not yield the resolution we favor. The book's goal is not to resolve the moral dilemmas raised. It is to raise them and encourage thought and discussion. It will ask but not answer why nearly all involved in agriculture have not addressed the moral concerns voiced by the general public. The agricultural enterprise is committed to the benefits and future success of the present, very productive, chemical, capital, and energy intensive system, which is, in the minds of many, not sustainable. The internal justification invokes the moral claim that they feed the world's population. The question remains whether or not the prevailing moral justification of feeding the world is adequate given all the issues modern, developed country agriculture faces: pesticides in soil, water, and food, cruelty to animals, Biotech/GMO's, corporate agriculture, pollution by animal factory waste, exploitation of and cruelty to migrant labor.

A wide-ranging scientific and cultural history of weeds that reveals just how interesting and useful these seemingly annoying plants can be. We spray them, pluck them, and bury them under mulch; and we curse their resilience when they spring back into place. To most of us, weeds are a nuisance, not worth the dirt they are growing in. But the fact is weeds are a plant just like any other, and it is only we who designate them as a weed or not, as a plant we will dote over or one we will tear out of the earth with abandon. And as Nina Edwards shows in this history, that designation is constantly changing. Balancing popular history with botanical science, she tells the story of the lowly, but proud, weed. As Edwards shows, the idea of the weed is a slippery one, constantly changing under different needs, fashions, and contexts. In a tightly controlled field of corn, a scarlet poppy is a bright red intruder, but in other parts of the world it is an important cultural symbol, a potent and lucrative pharmaceutical source, or simply a beautiful, lakeside ornament. What we consider a pest—Aristolochia Rotunda, or “fat hen”—was, in Neolithic times, a staple crop, its seeds an important source of nutrition. Sprinkled with personal anecdotes and loads of useful information, Weeds sketches history after history of the fashions and attitudes that have shaped our gardens, showing us that it is just as important what we keep out of them as what we put in, and that just because we despise one species does not mean that there haven’t been others whose very lives have depended on it.

Herbicides: Chemistry, Efficacy, Toxicology, and Environmental Impacts addresses contemporary debates on herbicide toxicology. The reader is offered a comprehensive overview of this complex topic, presented by internationally recognized experts. Information presented will inform discussions on the use of herbicides in modern agricultural and other systems, and their potential non-target effects on human populations and various ecosystems. The book covers these matters in concise language appropriate to engage both specialists in the research community and informed persons responsible for legislative, funding, and public health matters in the community at large. The use of herbicides is an essential pillar of modern agricultural production systems. Weeds, if uncontrolled, would reduce crop yield and result in massive economic damage. Recently, the heavy reliance on single herbicides has been linked to the development of weed resistance. To combat resistant weeds, farmers are advised to use a mix of several herbicides and to increase herbicide application rates. As a result, the toxicity of herbicides on human health and the environment has become a controversial topic. Offers a comprehensive overview of herbicide science in modern agricultural systems Addresses the complex problems that can arise from herbicide use and misuse, including weed resistance, pollution, and human health issues Uses recent examples to demonstrate the topical nature of this issue

This timely Handbook brings innovative, free-thinking and radical approaches to research methods in environmental law. With a comprehensive approach it brings together key concepts such as sustainability, climate change, activism, education and Actor-Network Theory. It considers how the Anthropocene subjects environmental law to critique, and to the needs of the variety of bodies, human and non-human, that require its protection. This much-needed book provides a theoretically informed analysis of methodological approaches in the discipline, such as constitutional analysis, rights-based approaches, spatial/geographical analysis, immersive methodologies and autoethnography, which will aid in the practical critique and re-imagining of Environmental Law.

Weeds pose a major challenge to the sustainability of agricultural production systems, causing significant crop yield, economic and environmental losses. Chemical weed control tactics play a major role in modern weed management, maintaining the productivity of diverse cropping systems, reducing yield losses and facilitating conservation agriculture. However, the over-reliance on chemical weed control has led to shifts in weed communities in agroecosystems which are now becoming dominated by high competitors and herbicide resistance. Thus, weed scientists and practitioners are urged to develop and incorporate innovative and feasible integrated weed management (IWM) systems that can reduce weed infestations and environmental impacts.
